After 25 years in IT and 10 years of Agile Coaching my current belief is that the most important thing to scale is engagement. There is no such thing as a successful change program without high levels of human engagement. Business Agility is about clarity of what you want to achieve and re-distributing authority throughout the organisation so the flow of decision making enables the flow of value. I believe Open Space Agility will help you achieve this.
